Russia and Ukraine derived revenues constituted 58%, how wil 2022 fare for Food Empire

$Food Empire(F03.SG)$ sgd 0.475. If operational costs remain unchanged but total revenue is affected by the war (let's assume, reduced by 50%), how will Food Empire fare in 2022? How long does it take to mitigate the risk by diversifying its market will less concentration on Russia and Ukraine? It is difficult to know without the next financial report... just my two cents
